Abstract
Method for identifying within an incident signal at least one frequency communication channel, the incident signal being received on a wireless apparatus, comprising determining a power spectral density (PSD) of that incident signal and identifying the at least one channel from the PSD. The PSD determination comprises storing temporal samples of the incident signal received during a predetermined duration and performing a first Discrete Fourier Transform (DFT) processing on the stored samples.
